[SOLVED] Unknown error

I am trying to create a Sardu ISO file using Sardu 2.

I have:

downlaoaded and installed Sardu 2
placed ISO files in Sardu_2/ISO folder
checked boxes of ISOs to include (2.74 Gb total; DVD can accommodate 4.7Gb)
click ISO-->Make ISO
I have chosen to save sardu.iso in the sardu_2 folder and subesquently on the desktop
When I click OK, Sardu begins extracting files.
at gparted, it asks for an OK to continue using 7z (I say yes)
It continues extracting files.
Extracts puppy, says everything is OK
then ERROR with no explanation

I tired substituting unbuntu for puppy - same ERROR
I tried substituting kbuntu for ubuntu --same ERROR
Finally I tried using no Linux distro at all -- same ERROR

I am using Win 7 Pro 64-bit with 8 gigs ram

Its like it cannot close the image.
image shows end screen. looks like process is complete, but no sardu.iso appears

What am I doing wrong?
please help

placed ISO files in Sardu_2/ISO folder <-- There is a space? --> Try to remove the space
at gparted, it asks for an OK to continue using 7z (I say yes) <<------SARDU don't ask ok to continue Gparted

You tested without ISOs?

You are so smart!

I eliminated gparted from the list
I changed folder name to Sardu/ISO
tested without ISOs --good
I am now the proud owner of a sardu disk.

Thank you so much.

Now work all? There are too many limits of programs DOS based (i use 7z for wxtracting file from ISOs)
